Paris Hilton's brother has been arrested for breaking into his ex-girlfriend Hunter Salomon's home — and if you're all wondering, yes, she's actually the daughter of Rick Salomon, the guy Paris made a sex tape with years ago.

Apparently Hunter is claiming that after the two broke up, the 21-year-old became scarily obsessive and started showing up at her house at the weirdest times.

She even claims Conrad threatened to kill himself.

Needless to say, the 19-year-old got a restraining order against her ex-boyfriend. However, on Monday, Conrad reportedly broke into her family home in the Hollywood Hills, which resulted in a ton of cops showing up to the house and arresting him.
